Figure 4. A resonant cavity supports only modes that meet the resonance condition, N = 2 × cavity length. The output of a CW laser is defined by the overlap of the gain bandwidth and these resonant cavity modes. If the laser diode operates on a 3-nm gain line, about 10 longitudinal modes, spanning 3…

…be applied to CW, pulsed and ultrafast lasers, greatly expanding the range of available wavelengths. Pulsed or ultrafast lasers have enough peak power (kilowatt range) to achieve relatively high conversion efficiency in a single pass through the harmonic crystal. On the other hand, CW lasers usually…

…broadening mechanisms widen the frequency (and energy) of the emitted photons. For example, free-running YAG lasers can have linewidths of hundreds of gigahertz, while stabilized diode-pumped YAG lasers can have a linewidth <1 kHz. The best known of these broadening mechanisms is the Doppler…

Risk factors: Except for the historical information contained here, many of the matters discussed in this Web site are forward-looking statements, based on expectations at the time they were made, that involve risks and uncertainties that could cause our results to differ materially from those expressed or implied by such statements. These risks are detailed in the “Factors That May Affect Future Results” section of our latest 10-K or 10-Q filing. Coherent assumes no obligation to update these forward-looking statements.
